When the shipper is again thrown 'on,the spring 36 p but the lever 33'and shield 30 will be retained by friction in the position shown in Fig.3, the lever 15 being simultaneously moved to position. for engagementwith the dagger 24. j n g t As the lay thereafter moves forward upon itsfirst beat after the replenishing of the filling, the absence of fillingin the shed will permit the fork 18 to'move downward andthe dagger 24willfollow the cam late 25 until it-engages the upperedge o the shield30. Such engagement however, will causethe dagger to pass over the endof the actuating lever 15. As the dagger .approaches the forward end ofits path of travel it will engage a projection upon the shield 30 andwill force theshield backward and downward to theposition shown in Fig.4.

Theloom will thereafter operate in the usual manner until a failureof-filling, when the dagger will engageth'e" lever 15 and stop the loomas has, been previouslydescribeda' M Theprovision of the cam roll 28 orthe cam surface 280 permits earlier engagement and disengagement of thedagger 24 and the lever 15 and this is found to be of substantialadvantage in certain looms in. whichitis impossible to turn the loombackward. after the lay has reacheda certain position inits on the lay,U H

said'filling fork and being adapted-to-nor- L forward movement. By theearlier engagement of the dagger '"with the actuating lever the limitsof movement of the lay after such engagement are correspondinglyincreased and the brakes may be permitted to act more gradually. Thisgradual application of the brakes has'bee'n found in practice tonoticeably" reduce the breakage of gear teeth and other parts, due tothesuddemstopping of'theloom; i" Having thus described my invention, itwill be evident that other changes andmodifications can'be made thereinby those skilled in the art without departing from the spirit and scopeof my invention as set'forth in the claims'and I do not wish'tobeotherwise limited to the details herein disclosed but what I claim isI 1; A center filling stop'motion' for looms comprising a shipper rod,an arm'on said "rod, a fixed stand, a--lever pivoted on 'said stand andengaging said arm to actuate the shipper, a filling fork: and daggermounted said dagger. g connected i to wi of th s intent ayt ben am.,acentseacl jp yjaddress ing the Commissioner of Patents, 1
